Benefits of technology
Enables accurate, non-intrusive, and remote analysis of Wi-Fi network performance, reducing support costs and enabling operators to diagnose and rectify issues without physical access, with 100% accuracy from the perspective of the network's access point.
Problems solved by technology
This widespread usage of wireless LAN has exposed however a serious downside of using a shared medium technology: interference.
Interference, both Wi-Fi and non-Wi-Fi related, leads to a degraded user experience due to the nature of 802.11.
Therefore, in certain circumstances, the Wi-Fi connection can suffer from poor performance and even connection loss.
For example, if the distance between the station and the access point is too large, then signal levels are low and performance will degrade.
A hidden node is invisible to some of the nodes of a network, leading to a practical failure of the CSMA-CA method which can cause packet collision / corruption over air.
In many cases, the end-user is not able to diagnose the problem source and correct the issue.
But the information available via TR-069 is very limited and focused on data traffic.
In some cases, an end-user is faced with an issue preventing Wi-Fi connection at all, correspondingly rendering TR-069 monitoring useless.
Hence, when an end-user calls a help-desk, it can be a lengthy and expensive process to describe the home topology and diagnose the issue at hand.
Full packet inspection is not possible, hence leaving technology or protocol analyzers in the dark when it comes down to pinpointing the real issues in a wireless LAN.
On Ethernet, this method of packet capture exists and is fairly trivial.
The software does however not visualize the low level Ethernet traffic but only the traffic above the physical layer.
Nevertheless, even on Ethernet one needs “more information”, if the link speed negotiation or duplex detection fails.

Embodiment Construction
[0020]In the following description, example methods for monitoring a wireless (Wi-Fi) link of a Wi-Fi node of a customer-premises equipment device are described. For purposes of explanation, various specific details are set forth in order to provide a thorough understanding of preferred embodiments. It will be evident, however, to one skilled in the art that the present invention may be practiced without these specific details.
[0021]A customer premises equipment (CPE) device includes for example a controller, e.g. a microprocessor, a non-volatile memory, in which an operating system is stored, a volatile memory for the operation of the CPE device, a Wi-Fi node for a wireless operation and a broadband connection, e.g. an xDSL connection. The Wi-Fi node includes a complex software driver, a physical layer with data buffers and an antenna. A CPE device of this kind is for example a residential gateway, which has a central position within a wireless local area network (WLAN).

The method for monitoring a wireless link of a Wi-Fi node of a customer premises equipment device comprises the steps of replicating receive packets as well as transmit packets passing through the transmit / receive buffers of a physical layer by including a time stamp for the replicated packets, and passing the replicated packets to a monitoring unit. All packets are replicated in particular by including an Rx / Tx control of the Wi-Fi software driver of the customer premises equipment device to obtain the exact packet exchange and timing of the Wi-Fi network. The customer premises equipment device comprises a Wi-Fi node including a Wi-Fi software driver and a physical layer with transmit / receive buffers, a Wi-Fi monitoring application for replicating the packets passing through the transmit / receive buffers, and a monitoring data path for passing the replicated packets to a monitoring unit.
Description
[0001]This application claims the benefit, under 35 U.S.C. § 365 of International Application PCT / EP2013 / 062888, filed Jun. 20, 2013, which was published in accordance with PCT Article 21(2) on Jan. 9, 2014 in English and which claims the benefit of European patent application No. 12305790.3, filed Jul. 2, 2012.TECHNICAL FIELD[0002]The invention relates to the field of customer-premises equipment devices including a Wi-Fi node coupled to an IP interface, e.g. via a digital subscriber line to a service provider.BACKGROUND OF THE INVENTION[0003]Residential gateways are widely used to connect devices in the home to the Internet or any other wide area network (WAN). Residential gateways use in particular digital subscriber line (DSL) technology that enables a high data rate transmission over copper lines or optical lines. During the years, several DSL standards have been established differing in data rates and in range, for example ADSL and VDSL, which are referred to in this context as...
